Patent DE-3902051-A1 (DE)
Title: Internal combustion engine with multi-cylinder combination
Inventor: MOSDELL RICHARD
IPC: F02B3/06
Filed: 1989-01-25
Abstract: The invention relates to the kinematic sequence of the crank mechanism of multi-cylinder/multi-chamber internal combustion engines with a view to reducing internal power losses due to inertia in the transmission of the combustion energy (impulse) to the transmission components - pistons, the connecting rods and the crank shaft. In the embodiments according to the invention of an internal combustion engine in the known four-stroke or two-stroke diesel engine, the four-stroke or two-stroke spark-ignition engine or the four-stroke Wankel engine, the control of gas exchange is characterised in that instead of the known ignition sequence of individual cylinders in succession in accordance with the cylinder number on the crank shaft, the power of a plurality of cylinders is combined, the said cylinders being fired simultaneously or with a delay, in order significantly to increase the combustion energy (impulse) and thereby reduce the inertia of the pistons, connecting rods, crank shaft, flywheel and drive components by division. A particular increase in power of the known Wankel engine may be expected from the embodiment according to the invention. This is based on the known constructional feature of the Wankel engine that the inertia of all the moving transmission components is relatively high and that a disproportionately high increase in power may be expected by increasing the instantaneous combustion impulse by duplication.
